Questions Washington drivers ask
How far can a Prologue go in a Washington winter?
About 244 miles on a typical January day (38°F) and about the same in the coldest week of the year (around January 16, 37°F on average), estimated from real EV drives at those temperatures. That's 11% below its 273-mile rating, mostly from heating the cabin and the battery.
How much does it cost to charge a Prologue in Washington?
About $111 a month at home for 38 miles a day, at Washington, DC's average home electricity rate of 25.2¢/kWh: about 9.6¢ a mile. An average standard SUV on the Central Atlantic's average gas ($4.31 a gallon) costs about $293 a month for the same driving.
Can I charge a Prologue on a regular 120 V outlet in Washington?
At 38 miles a day, most of the year: a 120 V outlet adds about 42 miles in 12 hours on an average day, but about 38 in the coldest week, so it can fall a little behind then. A 240 V outlet fills it from 10% in about 9 hours.
Is it greener to drive electric on Washington's grid?
Yes, more than most places. Washington's grid (RFC East) is 22% cleaner than the US average, so a Prologue charged on it makes 80% less CO₂ than an average standard SUV.
